Abstract: The embodiments relate to an apparatus and a method, where the apparatus includes circuitry configured for listening and receiving a positioning measurement request from a location server at a first point of time; circuitry configured for determining whether a set of positioning metrics need to be measured, wherein the determining is based on an output from a machine learning classifier to which channel metrics between two points of time is given as input; whether the output indicates a new measurement, circuitry configured for performing the measurement of positioning metrics from all transmission points; or if not, circuitry configured for determining which subset of transmission points needs to be measured and circuitry configured for performing the measurement of such subset of transmission points; and circuitry configured for reporting the measured positioning metrics to the location server.

Abstract: A method, apparatus and computer program is described comprising: obtaining reference signals received at a plurality of nodes of a communication system from a user device; generating signal signature matrices based on real and imaginary components of the obtained reference signals; and generating a first three-dimensional position estimate for the user device by applying signals based on the generated signal signature matrices to an input of a model.

Abstract: Inter-alia, a method is disclosed comprising: obtaining at least two sets of sample measurements, wherein a respective set of sample measurements thereof is indicative of one or more signals that are observable by an antenna, wherein a respective set of sample measurements of the at least two sets of sample measurements is measured with a respective antenna of at least two antennas, and wherein the two antennas have a distance from one another and are comprised by or connectable to an apparatus; determining time-of-arrival, TOA, difference information indicative of a TOA difference between the at least two sets of sample measurements, wherein the TOA difference information is determined based, at least in part, on at least two sets of sample measurements, the determining comprising checking whether the TOA difference reflects said distance between the at least two antennas. Corresponding apparatus, computer program and system are further disclosed.

Abstract: An apparatus, method and computer program is described comprising: receiving downlink positioning signals from each of a plurality of communication nodes of a mobile communication system at a user device of the mobile communication system, wherein each downlink positioning signal is received from a downlink beam direction for the respective communication node; determining an angle of arrival and/or a time of arrival for each of the received downlink positioning signals; and determining an uplink positioning signal beam configuration based, at least in part, on the determined angle of arrival and/or the determined time of arrival for said received downlink positioning signals.
